Hi, first off thanks for everyone's hard work. I am a long time lurker of mobileread. I registered because I am having trouble installing all the packages for the k4nt. I am using a k4NT that is jailbroken, and has custom screensavers.
I am trying to get custom fonts specifically, but none of the installers work for me. I copy the data.tar.gz file, and the update_"name here"_install.bin to the root, and select 'update your kindle'. Every time I get the same result "Update failed - please check error code below" the error code is U007. Can anyone help? Not sure what is wrong...
